Apparently A. anseris does not parasitize the Canada Goose, Branta 

 canadensis. I have been unable to find records of its occurring on this 

 species of bird and have not recovered it in 7 examinations of Canada 

 Geese.

The species name crassioornis and its subspecies are used to 

 designate those Anatioola found upon all Anatidae excluding the Cyginae, 

 Anserinae and the Dendrocyginae. Members of this species can be sep- 

 arated from A. anseris mainly by the shorter length of the penis. 



Length of penis (number of specimens in brackets) : 

 (from Clay and Hopkins, 1951) 



Anatioola orassioomis 0.13 (1), 0.15 (7), 0.16 (1). 



Anatioola anseris 0.27 (3).
